If the switch fails, the vehicle may begin braking without the driver's input, and without illuminating the brake lights, increasing the risk of a crash.

Service Brakes, Hydraulic — Pedals And Linkages

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2013 Lexus GS 350 vehicles manufactured June 8, 2012, through December 26, 2012. In the affected vehicles, the switch that senses the amount of pressure that the driver is applying to the brake pedal may fail.

Toyota will notify owners, and dealers will replace the brake pedal support assembly which includes the brake pedal load sensing switch, free of charge. Toyota sent owners an interim notification letter in late June 2014 to advise owners of the recall. Owners recieved a second letter after the remedy parts were available in mid-July. Owners may contact Toyota customer service at 1-800-331-4331.
